Abstract: The article is devoted to the measurement of environmental safety. The differentiation between the methodological concepts of safety and danger is carried out. The requirements for measures of environmental safety are substantiated. The correlation between safety and development, safety and danger is revealed. A quantitative approach to the environmental safety assessment is proposed. The objectives of environmental safety as a science and... More

Abstract: During coal mining and underground engineering, concealed structures such as fractured zones, abandoned roadways, mined-out spaces, and water-bearing disturbed zones pose significant safety risks. This study investigates a single-hole impulse borehole radar method for refined detection of such anomalies. A 20–200 MHz impulse radar probe is used for continuous acquisition during advancement along the borehole. Reflection travel time and... More

Abstract: Underground electrical infrastructure is gaining significance in response to urbanization and network densification, climate resilience requirements, and the broader energy transformation. However, even underground power systems are still regularly discussed within disciplinary silos, and there is little integration among engineering geology, geotechnical engineering, and electrical power engineering. This review establishes the concept of... More
